I'm using Orange PI PC board, OrangePI_Jessie_Xfce.img with kernel
3.4.39. I have two modems that both work on Raspberry Pi with Raspbian:
TRENDnet TFM-561U and USRobotics USR5637

I'm try to get /dev/ttyACM0 so I can use the modem with my python
scripts.

I can't get either to work. Any help or suggestions would be greatly
appreciated. All the information I could gather below:

Only the USR modem will be seen via lsusb:

# lsusb

As with nearly all the other images I think you are missing the kernel-modules. Whoever made the image didn't bother compiling all the drivers because they didn't need them themselves and thought no one else would need them either. You could check from /proc/config.gz what modules it was compiled with.

If it is missing the module(s) how would I go about installing it or them?

You must compile the kernel with the necessary modules and replace it in the system.
I just had to do to run a network card smsc7500.
